Old Chain of Rocks Bridge

Once part of Route 66—the Mother Road—this bridge across the Mississippi River was reopened in 1999 as one of the world's longest pedestrian/bicycle-only bridges.
On the Missouri side, access is by way of the St. Louis Riverfront Trail, a walking/biking trail beside the Mississippi River between the Gateway Arch and the Old Chain of Rocks Bridge.
This is a particularly scenic stretch of the Mississippi River, overlooking the natural chain of rocks, from which it derives its name.
Please note, there is no secure automobile parking on the Missouri side of this bridge. The parking lot on the Missouri side is closed, except for special events.
